any documents for optical fiber port chips VHDL practice
do not have enough money to buy expensive FPGA board with optical ethernet
would like to write VHDL code for optical ethernet
any IDE like Quartus and signaltap ii can do simulation
if have documents i can use Quartus and signaltap to do simulation?
how to measure the speed when do this kind of simulation in signaltap and Quartus of altera
